Abstract: A system and method for surface inspection of an object using optical coherence tomography (OCT) with anticipatory depth of field adjustment is provided. The method includes determining a present working distance and one or more forward working distances; determining a present depth of field in which the surface of the object is in focus at the location of the present working distance and at as many of the consecutive forward surface locations as determined possible; changing to the present depth of field; performing an A-scan of the object; moving the object such that the scanner head is directed at each of the consecutive forward surface locations determined to be in the present depth of field; and performing an A-scan at each of the consecutive forward surface locations determined to be in the present depth of field.

Abstract: A system and method for surface inspection of an object using optical coherence tomography (OCT) is provided. The method includes determining a surface profile of the object, the surface profile includes one or more regions on a surface of the object; moving the object relative to the OCT scanner head; and for each of the one or more regions on the surface of the object, performing: determining a working distance where the surface of the object at the respective region is within a present depth of field; determining an angle where the respective region is at the determined working distance from an OCT scanner head; directing the OCT scanner head at the determined angle towards the respective region when the respective region is at the determined working distance along the respective angle; and performing an A-scan of the object when the respective region is within the present depth of field.

Abstract: Embodiments described herein relate to systems and methods for specular surface inspection, and particularly to systems and methods for surface inspection comprising inverse synthetic aperture imaging (“ISAI”) and specular surface geometry imaging (“SSGI”). Embodiments may allow an object under inspection, to be observed, imaged and processed while continuing to be in motion. Further, multiple optical input sources may be provided, such that the object does not have to be in full view of all optical sensors at once. Further, multi-stage surface inspection may be provided, wherein an object under inspection may be inspected at multiple stages of an inspection system, such as, for an automotive painting process, inspection at primer, inspection at paint, inspection at final assembly. SSGI imaging modules are also described for carrying out micro-deflectometry.

Abstract: A system and method for acquiring imaging data of an object. The system includes a beam splitter for directing a derivative sample beam towards the object and a derivative reference beam towards a reflective element; a detector for detecting at least one of the returned reference beam and the returned sample beam; a mode switching module for selecting an operating mode between an optical coherence tomography (OCT) mode and a hyperspectral imaging (HSI) mode; and a computing module for receiving the detection from the detector and the mode from the mode switching module, wherein in the OCT mode, the computing device generates OCT imaging data by determining an interference pattern produced by a superposition of the returned reference beam and the returned sample beam, and wherein in the HSI mode, the computing module generating hyperspectral imaging data by determining hyperspectral information of the returned sample beam.
